Abstract

In a switch with multiple physical links to a destination, data is forwarded to the destination by distributing received data across the physical links. A flow hash is selected for the received data's data flow dependent on a destination address and source address included in the received data. The flow hash selects one of the physical links to the destination for a data flow but potentially a different physical link for a different data flow, thereby forwarding the received data by distributing the received data across the physical links while maintaining frame ordering within a data flow.

Description

(57) In a switch with multiple physical links to a destination, data is
forwarded to the destination by distributing received data across the physical links. A flow hash is selected for the received data's data flow dependent on a destination address and source address included in the received data. The flow hash selects one of the physical links to the destination for a data flow but potentially a different physical link for a different data flow, thereby forwarding the received data by distributing the received data across the physical links while maintaining frame ordering within a data flow.
